I bought this a while ago but have never worn it. I have a wedding this weekend. I don't know the couple very well so don't know how formal their wedding is.
Is this dress ok or is it too close to white/ tea length wedding dresses?
I'm rubbish at this kind of thing and wouid hate to upset someone.
Thanks

I also think it looks like a bridesmaid's dress. It's lovely though.

Looks nothing like a bridesmaid dress or apart of bridal party.

If you like it op, then go for it.

i don't think**
